Hansberry understanding of summer changed through out the story. In the first part she felt as though summer was a mistake and she wasn’t feeling summer as much. but towards the end she saw summer as the “apex of life”.
In cells, some genes are constitutively transcribed. These genes are typically under damped feed forward and positive control mechanisms and their protein products code for basic metabolic machinery and other proteins necessary for cell life. If they weren't there, the cell would die; therefore, it is careful to always transcribe enough new mRNAs to replace those being degraded.
In cases when more of these products are needed - for example, when a cell faces a metabolic challenge - then transcription is upregulated from this basic or basal level. The cell meets its need; negative feedback at higher transcript concentrations or copy number reduces transcription of the gene or genes involved in the response, and their rate of transcription goes back to the basic level.
For a superb example, read up on hypoxia inducible factor and the cassette of genes it regulates.
U didn't give us options, but if Establishing a main idea or message is an answer choice...go with that. A rhetorical device is a technique or a tool used in speaking that focuses on the introduction of the speech and this are an unusual and a dramatic speech. The listener will understand the message....hope i helped

Dear _________ (Name of the Receiver),
It has been a long time since I wrote to you. How is life? How is everything back home? How is uncle’s health now? I Hope all is well at your end.
This year started on a good note for all of us. My family and I went on a trip to Bangkok. It was an enjoyable experience, and the family got a good time to spend together. I think it was last year’s Christmas blessings that the trip went on well. It has been a long time since I met you. Why don’t you visit our house during this Christmas season along with your family? I am sure kids would love it.
I want to celebrate this occasion with my dearest people since this is an occasion for friends and families to exchange gifts and best wishes. We will have a great time.
I am looking forward to meeting you soon.
Yours truly,
___________ (Name of the Sender)
hope it help friends
